Heat Transfer: the movement of energy from a warmer object to a cooler object Density: The measure of the amount of mass there is in a volume of a substance Radiation: The transfer of energy through empty space Conduction: Heat transfer by direct contact through particles of matter Convection: Heat transfer by the movement of a heated fluid Convection Currents: The flow that transfers heat within a fluid
Outline
Summary
Heat form core affects mantle using convection currents
Three heat transfers- Radiation, Conduction, and Convection
Convection Currents in Earth for more than 4 billion years
Radiation
Heat Transfer through empty space
No direct contact
Conduction
Direct contact of particles of matter
Heat goes to cold, not visa versa
Convection
Movement of heat in a fluid
Convection currents
Gets heated, hot moves to top, goes to bottom, and then gets re-heated
